Calculation Methodology

Tiered Bill = Fixed Monthly Customer Charge + (Baseline kWh * Tier 1 Rate) + (Excess kWh * Tier 2 Rate) + Mandated Regulatory Fees. TOU Bill = Fixed Charge + (On-Peak kWh * On-Peak Rate) + (Off-Peak kWh * Off-Peak Rate) + Regulatory Surcharges.

Frequently Asked Questions

Tiered pricing charges based on total volume of electricity consumed during the billing cycle (Tier 1 baseline vs Tier 2 higher rate). TOU pricing charges based on WHEN electricity is used, with expensive rates during high-demand peak hours (e.g., 4 PM to 9 PM on weekdays) and cheaper rates during off-peak hours and overnight.
